Title: Transistor type switching circuit
Inventor: MATSUMURA TAKASHI
IPC: H01L21/331
Filed: 1978-06-09
Abstract: PURPOSE:To shorten the accumulation time of a switching transistor even in a fine-current region and also to prevent its malfunction by providing a discharge passage of a transistor and resistance betweem the base and emitter of the switching transistor. CONSTITUTION:Once the base current of switching transistor 1 is cut off, charge accumlated in the base-emitter junction of transistor 1 is discharged by way of resistance 5 and the base of transistor 3. As a result, transistor 3 turns ON to flow a collector current, equivalent to a current obtained by multiplying a base current by a current amplification factor, as a discharge current. The sum of this discharge current flowing momentarily is between tens pice to several nano A. The accumulated charge is therefore discharged without being limited by resistance 4 and transistor 1 can immediately be turned OFF. In this way, a high-speed switching circuit can be obtained which has its accumulation time shortened even in a fine-current region and is hard to malfunction.

Title: Transaction processor
Inventor: TANABE YASUHIRO
IPC: G06Q20/40
Filed: 1986-03-27
Abstract: PURPOSE:To simplify the operation of transaction processing by storing the information showing a transaction enable period despite no input of an identification number to an IC card and discriminating said stored information to carry out the transaction. CONSTITUTION:The information showing a transaction enable period is stored even though no identification number is supplied to an IC card. This information stored in the IC card is read by a card reader 3. A CPU 1 checks whether the date received from a date data generating means is kept or not within the period read by the card reader 3. Then the CPU 1 requests the input of an identification number as long as said date is out of the prescribed period despite no input of the identification number. While no request is given for the input of the identification number if the date is within said period despite no input of the identification number. Then the transaction processing is carried out.

Title: Image-forming lens positioning mechanism in copying device used as image-forming type or contact type
Inventor: YOSHIHARA HIDEO
IPC: G03B27/34
Filed: 1988-03-24
Abstract: PURPOSE:To position an image-forming lens efficiently by placing a transparent reflecting plate between a film plane and a light source part, optically detecting the slide film plane by means of photoelectric transfer elements to focus it at the time of forming and exposing an image, and optically detecting the transparent reflecting plate in contact exposure. CONSTITUTION:The mechanism has a light source and a pair of focus detecting elements 10A and 10B, the light source emitting light onto the transparent reflecting plate plane 4 or the slide film plane 5 in order to focus, and the pair of focus detecting elements receiving the light from the light source. When an image is formed and exposed on a slide, the focus detecting elements 10A and 10B detect the slide plane and then move the holder 6A of the image-forming lens 6 in response to a detected signal to stop it at the position where the slide plane is focused. There are no slides in contact exposure, so that they detect the transparent reflecting plate plane 4, placed behide the slide, and stop the image-forming lens 6. Thus, even if the film plane is warped by the heat of the light source at the time of forming and exposing the image, the image is copied satisfactorily; and in the contact exposure, the positioning of the image-forming lens is ensured by the transparent reflecting plate.

Title: Filthy water disposal and apparatus for filthy water disposal
Inventor: NAKAMURA SHIYUUICHI
IPC: C02F1/465
Filed: 1983-04-21
Abstract: PURPOSE:To efficiently perform the actions of electrolysis and filtration at the same time for the removal of contaminants, by supplying filthy water to the interior of a tubular electrode comprising porous carbon, and impressing DC voltage between both electrodes to separately float up contaminants. CONSTITUTION:A proper amount of filthy water 31 is supplied through a supply opening 6 to a filthy water tank 15 inside a filthy water disposal tank 1, and DC voltage is impressed between a tubular electrode 4 as a cathode and a columnar electrode 5 as an anode. When the filthy water 31 is bilge, i.e. sea water containing oil drops, the DC voltage to be impressed is about 20V, and an electric current to be applied is 3-5A. Hence, gas is formed by the action of electrolysis, fine gas bubbles rise upwards through a gap between the electrodes 4 and 5, and oil drops adsorb said gas bubbles and coagulatively float up to the upper part of the filthy water tank 15. On the other hand, since hydraulic pressure is applied to the inner cavity of the tubular electrode 4, the filthy water being affected by the action of electrolysis penetrates into the tubular electrode 4. Hence, said water is received as treated water from which contaminants have been removed in a treated water tank 16.
